A dynamic imbalanced force generator includes a pair of eccentric masses and a shaft frame. The generator further includes at least one support plate of a motor arranged radially with respect to the shaft frame, and a gear system. A second imbalance is arranged between a first imbalance and the shaft frame, and coaxially with respect to the first imbalance. At least one motor is supported by the plate and engaged with at least one of the first and second imbalances by the gear system. The support plate and the motor are arranged between the imbalances and the shaft frame.

Dynamic imbalanced force generator and an actuator comprising such a generator

Provided is a dynamic force generator having a supporting shaft, a first rotor including an internal bore housing the supporting shaft and bearings arranged between the supporting shaft and the internal bore so that the first rotor is mounted rotatably in relation to the supporting shaft, an external bore having an inner face provided with a first set of permanent magnets. A first unbalanced mass is within the internal bore of the first rotor and mounted opposite an outer face of the external bore of the first rotor. A second rotor is mounted rotatably in relation to the first rotor, via an antifriction component provided between the first rotor and the second rotor, and includes an internal bore housing the internal bore of the first rotor so that the internal bores of the first and second rotors are concentric, and an external bore with a second set of permanent magnets.
